My purpose is to download the advertising report,
but I encounter Advertising API issue on below step 4 of Authorization,
When I access below my url, I should get the authorization code but get error message‘error_description=An+unknown+scope+was+requested&error=invalid_scope’ rather than the authorization code .
by the way, this account also is the seller account and has approvaled the advertising API access,
what should I do？
